Florida CirTech Inc has developed CK300-Catalyst Killer. The product is an acidic liquid concentrate that is a highly concentrated. Developed to clean printed circuits before the Electroless Nickel Immersion Gold (ENIG) process, CK300 is reported to remove palladium catalyst residues and other surface contaminates.
 
CK300 contains sulfuric acid and fluorides, but no alkyl phenol type surfactants. It also eliminates ENIG plating in non-plated through holes.
